Eliminating Belief in Favor of Knowledge

Response to a question about my discussion with  @drpeterboghossian  here: https://youtu.be/72vhtT0pFmA?si=hAx1kPho4DkLkBFN This is yet another way of coming at a critique around the concept of "belief" or those who profess to "believe" and so on using Deutsch's approach that knowledge is "information with causal power". I explore that for around the first 40 mins. If you're in a hurry, skip to the final 15 or 20 minutes where I get to responding to the meat of the matter in the question itself.
